EMMANUEL LA VALLEE, OF PAWTUCKET, RHODE ISLAND, ASSIGNOR TO LORRAINEMANUFACTURING COMPANY, A CORPORATION OF RHODE ISLAND.

SHUTTLE.

Application filed July 10, 1915.

To all whom it may concern Be it known that I, E MANUEL LA Var.- LEE, acitizen of the United States, residing at Pawtucket, in the county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvements n Shuttles, of which the following is a spec1-lication, reference being had to the accompanying drawings, forming partthereof.

This invention has reference to impro ements in shuttles for loomswhereby the side walls of the shuttles are continuous throughout andparticularly at the points corresponding to the axis on which thespindle is adapted to swing.

A further object of the invention is to simplify the construction ofloom shuttles with particular reference to the mounting of the spindle.

Other objects of the invention will appear from the followingdescription.

The invention consists in the novel bearing for the spindle pivot.

The invention also consists in such other novel features of constructionand combination of parts as shall hereinafter be more fully describedand pointed out in the claims.

Figure 1, represents a plan view of a loom shuttle illustrating thisimprovement. Fig. 2, represents a longitudinal sectional view of partsof the same taken on line 2-2 Fig. 1. Fig. 3, represents a detailsectional view of parts of the shuttle taken on line 3-3 Fig. 1.

Similar characters of reference designate corresponding partsthroughout.

In carrying this invention into practice in the preferred form hereinshown I take a shuttle body A of a conventional shape ex-' teriorily andhaving the usual bobbin receiving cavity B. At one end of this cavity Band extending in line therewith I provide the recess or compartment Chaving the side walls D, D and the end wall E having the depressed'top fand the shoulder g. The side walls D, D have the slots (Z, (Z whichcommunicate with the U-shaped seats 6, c constituted by semi-circulargrooves, spaced from the inner surfaces of said walls D, D to receivethe U-shaped metallic bearing members 5, 5 the arms of which aresemicircular in cross section.

The bobbin carrying spindle 6 has the in- Specification of LettersPatent.

tegral base 7 having the cam shoulder 8, the stop finger 9, and thetransversely extending pivot pin 10 the ends of which are slidably androtatably received by the bearing inenr bers 5, 5. In order to retainthe base 7 and its spindle 6 in the shuttle I provide the recess C withthe spring plate 11 secured in place by the screw 12 so that one end ofsaid plate 11 rests against the depressed top f while the other endbears against the cam shoulder 8, of the spindle base 7 whereby, whenthe spindle is in the position shown in the drawings, to press the stopfinger 9 of said base 7 against the shoulder g of the shuttle recess orcompartment C. When the free end of the spindle 6 is swung upward, as inchang ing bobbins, the plate 11 cooperates with cam shoulder 8 tosustain the spindle in such position.

By reference to Fig. 1 of the drawings it will be noticed that the endsof the pivot 10 do not extend to the outer surfaces of the shuttle wallsand cannot be displaced to positions where said pivot can act againstthe loom reed or any exterior part relative to which the shuttle isadapted to be moved.

Tie U-shaped bearing members 5, 5 for the spindle pivot pin 10 aredurable and are effectually retained by their seats 0, 0. These bearingmembers also facilitate the withdrawal and replacement of the pivot pin10 with the spindle 6.

Having thus described my invention I claim as new and desire to secureby Letters Patent- I A shuttle having a spindle receiving cavity and acontracted recess extending from said cavity and having an end wallfurnished with a stop shoulder and side walls having grooves, U-sliapedseats of semi-circular cross section in the shuttle body spaced from thewalls of said recess, U-shaped bearing members having semi-circular armspermanently located in said seats, a spindle having a base furnishedwith a cam shoulder and a stop finger, a pivot pin extendingtransversely of said spindle base and having its ends slidably androtatably received by said bearing members, and a spring plate securedin said recess and bearing against the cam shoulder of said spindlebase.
